Abstract

The invention provides a silage method of gramineous forage grass and medicago sativa. According to the silage method, the water content of mixed materials of the medicago sativa and the gramineous forage grass is controlled by straw, the air-drying time is shortened, the making of a silage fodder is accelerated, besides, the nutrient components of three feeds are used for benefiting each other, and waste resources are used, so that the added value of the waste resources is increased, the content of sugar in the mixed silage raw materials is increased, the content of the crude fat is increased, the palatability is improved, the quantity of lactic acid bacteria is increased, or bad fermentation is restrained, and the fermentation quality and the nutrient content of the silage are further increased.

Description

technical field [0001] The invention belongs to the technical field of grass processing, and in particular relates to a method for silage of grass grass and alfalfa. Background technique [0002] Alfalfa is recognized as an excellent leguminous forage in the world. After silage, alfalfa has good palatability and high digestibility. The crude protein content of high-quality alfalfa silage is more than 18%, and it is also an important source of vitamins, especially carotene and some unknown factors. source. [0003] Silage is lactic acid bacteria fermented feed. Natural silage is fermented by lactic acid bacteria existing on natural plants. Due to the low content of lactic acid bacteria on natural plants, it only accounts for 0.01-1% of the total number of bacteria. Therefore, during the fermentation process, it is difficult for lactic acid bacteria to quickly form a dominant flora and cannot lower the pH value in a short time. The results: one is that various bacteria are g...
